CCXXXVIII

CCXXXVIII is the Roman numeral representation of the number 238. It is formed by combining the symbols C (100), C (100), XXX (30), and VIII (8) to yield 238.

In Roman numeral notation, CCXXXVIII is additive, meaning it is constructed by summing values rather than using subtractive notation. The numerals involved are C (100), X (10), V (5), and I (1), with no subtractive pairs such as IV or IX needed to express this number.

Historically, Roman numerals originated in ancient Rome and remained in common use throughout the medieval period for inscriptions, monuments, and various record-keeping tasks. In modern contexts, CCXXXVIII may appear on clock faces, in chapter or volume numbering, in film or publication sequels, or in the regnal or papal numbering where Roman numerals are customary.

Mathematically, 238 factors as 2 × 7 × 17. In calendrical terms, the 238th day of a common year is August 26, while in a leap year it is August 25, illustrating how such numbers interact with ordinal counting in everyday timekeeping.
